Download K-Lite Codec Pack

There are four different variants of the K-Lite Codec Pack. Ranging from a very small bundle that contains only the most essential decoders to a large and more comprehensive bundle. The global differences between the variants can be found below. Detailed differences can be found on the comparison of abilities and comparison of contents pages.

These codec packs are compatible with Windows XP, Vista, Windows 7, 8, 8.1 and 10. The packs include 32-bit and 64-bit codecs, so they work great on both x86 and x64 variants of Windows!
